  • Patent number: 8057104
    Abstract: The angular contact roller bearing has an outer bearing ring, an inner bearing ring, a plurality of ball rollers arranged between the rings, and a bearing cage. The ball rollers in the two adjacent rows have pressure angle axes extending parallel to one another and are arranged directly one next to the other with their side faces point toward one another. Adjacent ball rollers in the two rows are arranged on a common rotational axis. The ball rollers have diameters and widths which are dimensioned in such a way that envelope cones which form tangents with all the ball rollers at their diameters are arranged with their cone tips precisely at the intersection point of the common rotational axes of the bearing longitudinal axis.

  • Patent number: 6367979
    Abstract: In order to allow a ball bearing to be inserted into a housing which is closed at one end, without any bearing parts being damaged during the axial insertion process, the outer ring of the bearing has a radially inwardly directed flange that extends radially into the region of the inner ring while toward the open end of the housing, the inner ring is formed on the axially outward side of the bearing balls, without a shoulder on the inner ring. An axial compression spring is arranged between the closed end of the housing and the inner ring. The flange on the outer ring may be either axially inward of or axially outward of the row of bearing balls.

  • Patent number: 5150973
    Abstract: A mounting sleeve particularly for the loose annular parts of a multi-row anti-friction bearing wherein the rows of rolling bodies are toward the axial ends of the outer ring. The mounting sleeve is approximately U-shaped with a slit opening of about 90.degree. in it extending along the sleeve. At axially opposite ends of the U-shaped sleeve are formed radially inwardly directed flanges which extend over a smaller circumferential angle than the sleeve, e.g. over an angle of about 180.degree., and are each symmetric around the U-shaped sleeve. Projections on the axial insides of the flanges rest axially either against the row of rolling bodies or against the separators for the row of rolling bodies. A radially outward projection opposite the slit opening in the sleeve aids in installation and removal of the sleeve.
